Brain tumors can be treated with the laser. The CO 2 laser may be used in several ways. Massive or well‐encapsulated tumors may be removed in the usual way and the remnant vaporized by the laser from the depth, dura, or cranium. If the tumor is superficial and not massive, it may be vaporized with the laser immediately. Deep‐seated tumors may be exposed by incising the overlying cortex with a focused laser beam and the tumor then treated by conventional means or with the laser or both. Cystic tumors must be aspirated and then the laser used to vaporize the cyst wall. Wet cotton pads should be used to protect the brain. The experience with nine brain tumors is reported, pointing out advantages and disadvantages of the laser. A 300 watt CO 2 was used for treatment. Measurement of the temperature of the brain 0.5 cm. from the point of vaporization is reported.
